Number of CPU's
Any way to get access to the number of CPU's, optionally their type,
from within R? In linux I can just read /proc/cpuinfo but for
win/mac ?
Thanks!

[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
Testing on an 8-node 128-way NUMA machine has exposed a problem with
Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized
CPUs at 32, the machine appears to have 16 CPUs on the first and second
nodes and none on the remaining nodes. Given this asymmetry, the
calculation of sockets_per_node (which is later used to calculate
nr_cpus) is incorrect:
